Description

Technical Field

[0001] This utility model relates to the field of plastic bag punching technology, specifically a punching machine for plastic bag production. Background Technology

[0002] During the production process, plastic bags may need to be perforated. Generally, a hot melt punching machine is used to punch holes in plastic bags.

[0003] Current hot melt punching machines mainly use heating elements to melt the perimeter of the punching area on the plastic bag, forming the required hole. This process usually involves high-temperature rapid heating to achieve a precise and fast punching effect. However, a major drawback of the existing technology is that the waste film generated during the punching process, i.e., the material residue after melting, often adheres to the lower end of the heating element due to the stickiness of the melted part. At this time, the operator needs to manually remove it with tools such as pliers or tweezers before proceeding to the next punching operation, thus reducing the overall production efficiency. Therefore, it is necessary to design and modify the punching machine used for plastic bag production to effectively prevent the phenomenon of high punching efficiency. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 4As shown, a punching machine for producing plastic bags includes a base plate 1. A workbench 2 is fixedly connected to the top of the base plate 1 via a bracket.

A square tube 10 is fixedly connected to the bottom of the workbench 2 via a bracket. The cleaning frame 11 is slidably connected inside the workbench 2. The cleaning frame 11 is set with a guide angle on the side near the opening 7. The bottom of the workbench 2 is provided with an annular groove, and a toothed ring frame 12 is slidably connected inside the annular groove. An adjusting block 13 is fixedly connected to the inner wall of the toothed ring frame 12. There are several adjusting blocks 13, which are evenly distributed in a ring on the inner wall of the toothed ring frame 12. The bottom of the workbench 2 is fixedly connected with a motor 14. The output end of the motor 14 is fixedly connected with a gear 15, which meshes with the toothed ring frame 12. The hot melt rod 6 mentioned above is similar in principle to the hot melt rod mentioned in Chinese Patent Application No. CN202420307075.3 (A punching machine for producing biodegradable and environmentally friendly plastic bags), and achieves the same effect. It is an existing public technical means in this field, and will not be described in detail here.

[0021] refer to Figure 2 and Figure 4 The bottom of the workbench 2 is provided with a sliding groove, and a connecting rod 16 is slidably connected inside the sliding groove. There are several sliding grooves, and the sliding grooves are evenly distributed in a ring at the bottom of the workbench 2. The bottom of the connecting rod 16 is fixedly connected to the top of the cleaning frame 11.

[0022] As a technical optimization of this utility model, by setting up a sliding groove and a connecting rod 16, the connecting rod 16 slides stably in the sliding groove and is fixedly connected to the cleaning frame 11, thereby improving the stability of the cleaning frame 11 when it moves.

[0023] refer to Figure 2 and Figure 4 The bottom of the workbench 2 is fixedly connected to a fixing block 17. There are several fixing blocks 17, which are evenly distributed in a ring at the bottom of the workbench 2. A compression spring 18 is fixedly connected to the surface of the fixing block 17. The end of the compression spring 18 away from the fixing block 17 is fixedly connected to the connecting rod 16.

[0024] As a technical optimization of this utility model, by setting the fixing block 17 and the compression spring 18, the compression spring 18 always applies a spring force away from the opening 7 to the connecting rod 16 and the cleaning frame 11, so that the cleaning frame 11 always fits against the inner wall of the toothed ring frame 12.

[0025] refer to Figure 1 A guide tube 23 is fixedly connected to the bottom of the square tube 10.

[0026] As a technical optimization of this utility model, the guide tube 23 can guide the falling film so that the film waste falls accurately into the collection box 25.

[0027] refer to Figures 1 to 3 Telescopic rods 19 are fixedly connected to the bottom of the movable plate 5 around its four sides. A pressing frame 20 is fixedly connected to the bottom of the telescopic rods 19. An anti-slip pad 22 is fixedly connected to the bottom of the pressing frame 20. Springs 21 are fixedly connected to the bottom of the movable plate 5 around its four sides. The end of the spring 21 away from the movable plate 5 is fixedly connected to the pressing frame 20. The surface of the spring 21 is coated with anti-rust paint.

[0028] As a technical optimization of this utility model, by setting up the telescopic rod 19, the pressing frame 20, the anti-slip pad 22 and the spring 21, the operator can lay the plastic bag to be punched flat on the top of the workbench 2. When the movable plate 5 moves down, it drives the telescopic rod 19, the pressing frame 20 and the anti-slip pad 22 to move down, thereby pressing the plastic bag tightly on the top of the workbench 2, preventing the plastic bag from shifting when punching the bag, thereby improving the accuracy of punching.

[0029] refer to Figure 1 Sliding strips 24 are slidably connected to both sides inside the base plate 1. A collection box 25 is fixedly connected to the top of the sliding strip 24. A handle is fixedly connected to the front of the collection box 25. The surface of the handle is provided with anti-slip textures, and the number of anti-slip textures is several. The front of the sliding strip 24 extends to the front of the base plate 1.

[0030] As a technical optimization of this utility model, by setting up the sliding bar 24 and the collection box 25, the collection box 25 can collect film waste. The operator can pull out the collection box 25 until the sliding bar 24 separates from the bottom plate 1, and then clean the waste in the collection box 25.

[0031] The working principle and usage process of this utility model are as follows: In use, the operator first places the plastic bag to be punched on the top of the workbench 2, then starts the electric cylinder 4 to extend, thereby driving the movable plate 5 to move downwards. The anti-slip pad 22 first contacts the plastic bag, and then the movable plate 5 continues to move downwards. At this time, the spring 21 is compressed, and the clamping frame 20 presses the plastic bag tightly. Then, the hot melt rod 6 contacts the plastic bag. After the hot melt rod 6 contacts the plastic bag, it stays for 3 seconds, and then the hot melt rod 6 continues to move downwards to punch holes in the plastic bag. The bottom of the hot melt rod 6 and the film waste move down to below the opening 7, and the hot melt rod 6 stops heating. At this time, the bottom of the hot melt rod 6 is at the same level as the top of the cleaning frame 11. Then, the air pump 9 is started, causing the nozzle 8 to spray airflow, thereby cooling and solidifying the film waste at the bottom of the hot melt rod 6. The air outlet of the nozzle 8 is tilted downwards, which can blow the film waste from the bottom of the hot melt rod 6 and let it fall into the collection box 25. When the film waste is still sticky... When attached to the bottom of the hot melt rod 6, the operator starts the motor 14 to rotate, which drives the gear 15 to rotate, and in turn drives the gear ring frame 12 to rotate about 30 degrees. From a downward view, the gear ring frame 12 drives the adjusting block 13 to rotate counterclockwise. The adjusting block 13 pushes the cleaning frame 11 to move closer to the opening 7. The cleaning frame 11 can scrape off the film waste adhering to the bottom of the hot melt rod 6. The scraped film waste falls into the collection box 25. Then the motor 14 rotates in the opposite direction, which drives the gear ring frame 12 and the adjusting block 13 to rotate in the opposite direction and reset. Under the action of the compression spring 18, the cleaning frame 11 moves away from the opening 7, so that the cleaning frame 11 resets. This cycle is repeated. This device can effectively clean the film waste on the surface of the hot melt rod 6, thereby avoiding poor drilling effect due to the adhering waste on the surface of the hot melt rod 6. At the same time, it avoids the large amount of manpower and time wasted on manually cleaning film waste, thereby improving the drilling efficiency of the device.
